Abstract

Heavy metal pollution is a problem and the developing in the world. HEAVY METALS such as lead, copper, cadmium and nickel are among the most common pollutants found in industrial wastewater. The main objective of this study was to determine the efficient removal of HEAVY METALS lead, cadmium, nickel and chromium in AQUEOUS SOLUTIONS using DUCKWEED. Also, the inhibitory effect of HEAVY METALS on plant growth was also examined. Applied research project is based on empirical studies. In this study, heavy metal solutions were prepared at concentrations of 10 milligrams per liter. To contact the crockery plant with heavy metal solutions were used. Duck weed Weight (0.8 grams) was added to the containers. After a contact time of 10 and 15 days, the amount of HEAVY METALS remaining in solution was measured by ICP instrument at the Rasht Health Department. After this time DUCKWEED weight was also measured. The results showed that the contact time of 10 days every 4 heavy metal removal efficiency greater than 15 days. The removal of lead is greatest (87.83%) and the removal of Chromium is lowest (61.94%). The maximum removal of lead and cadmium and nickel is related to. The study also showed that each of the four HEAVY METALS decreased the growth of DUCKWEED screw. This slowdown is greater for chromium. HEAVY METALS removal is possible with DUCKWEED. Factors affecting the rate of removal are appropriate time and Type of metal. The removal of lead is greatest and the removal of Chromium is lowest
